“It's not about killing monsters, looting treasure, and gaining experience as you delve deeper into some mad archmage's architectural folly. It's about surviving in a loathsome, terrifying environment where nothing is quite as expected. It's about atmosphere, gloom, and despair. It's a thriller.”

Awesome book, and very happy with the purchase (I chose the hardcover + PDF). Any chance you could make a printer friendly version available? I want to print out the worksheets at the back (rather than writing in the book itself), and it would be brilliant to either have them available as a separate download, or put layers on the PDF, or just a version of the PDF with a plan white background.

Also, a quick question: You say that the castle is about the same size as the Palace of the Parliament in Romania. Am I right in telling my players that's more-or-less 800 feet by 900 feet?

PUBLISHER

That's a little bit less than 800'x900', but almost so yes, that's right-ish. Thank you! You could maybe print the worksheets as they are for the moment, it's been a long time I have a printer-friendly and/or Lulu revision in mind, but it's tanking big time under new juicy projects.

Another awesome offering from Kabuki Kaiser. This is weird enough while still holding that traditional fantasy feel of a Fairy Tale gone off its rocker!

I almost don't want to ask this, but would this work solo?

Patrice CJanuary 12, 2016 8:54 am UTC

PUBLISHER

This probably would work with a bit of imagination, but it's not specifically intended for solo play as Ruins of the Undercity or Mad Monks of Kwantoom are.

I don't really get it. Is there no map?

Patrice CNovember 10, 2015 1:14 pm UTC

PUBLISHER

There are mini-maps for all the Gold sections, these are more like your traditional adventures. Otherwise, everything is determined randomly and sprawls on in a theater of mind kind of adventure. It's the players duty to maintain the upkeep of the map.

PURCHASER

So how many maps are included?

Patrice CNovember 20, 2015 8:31 am UTC

PUBLISHER

Didn't you buy it? There are 5 maps of small areas (about 7-9 rooms each) and 2 maps of a single area each. These maps correspond to mini-dungeons within the castle.

Is it playable with S&W Whitebox rules?

Patrice COctober 26, 2015 4:33 pm UTC

PUBLISHER

It is, the stat blocks are thin and generic so that you can use it with every OSR system with minimum to no hassle.

Thanks for the quick reply!

Any chance the POD version will go to Lulu? RPGNOW's POD service can't seem to send out books without them being horribly damaged...I don't seem to ever have that problem with Lulu...

Patrice COctober 26, 2015 4:33 pm UTC

PUBLISHER

Not in a near future because Lulu and OBS have different formats, which means that I'll need to format everything again if I need to do it. I might but not soonish.

Dwight FOctober 30, 2015 2:20 am UTC

I also toss my hat in for Lulu or well, anyone but OBS. Looks like a great product but I don't really want to throw money at OBS.

Patrice COctober 30, 2015 4:12 am UTC

PUBLISHER

Well, you are on OBS so that only makes sense to find it here. I'll do my best for Lulu at some point.

"The biggest dungeon ever published by the OSR."

Do you mean biggest dungeon or biggest dungeon?

Patrice COctober 23, 2015 8:05 am UTC

PUBLISHER

Not big like it has 1,000 rooms. Big like this:
"Castle Gargantua is about the same height as the Empire State Building and the same size as Ceausescu's Palatul Poporului in Bucarest, a little bit over three million square feet, the same size as the entire old city of Venice. Its rooms and corridors are so huge that condensation clouds of mist hover within and that it rains inside sometimes. There are miniature tornadoes in the spiral stairs and strong drafts of wind when the corridors are slightly sloped. If a curtain would fall, its weight alone would smash a dozen men to a pulp.'

I dunno, the Patala Underworld of Arrows of Indra seems larger. It's basically the whole under part of the Earth

Or you could imagine megadungeons the size of a whole star system, but that wouldn't make them playable straight from the book without prep or give you all the details you need to run them.

This is a wonderful little toolkit for building your own megadungeon, and I can say from personal experience that it works really well at the table to generate a dungeon on-the-fly. Some caveats: I would recommend reading the whole thing through first [...]

Excellent production value, design and writing. The game offer you a randomly generated and ever changing MEGA dungeon and totally deliver it. Generating the dungeon on the fly while playing also work well and better than the previous books of the same [...]

+Kabuki Kaiser has hit it out of the park again with the latest release of Castle Gargantua. Castle Gargantua builds on some of the mechanical ideas of procedurally generated adventuring that were featured in Ruins of the Undercity and The MadMonks [...]

These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.

Original electronic format

These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
